How to mock an external server for a client unit test

[javier.g...@gmail.com]

Hi,
I am trying to write some unit tests for a client application using an external service.

I just want to test my client functionality, error handling, etc.

Reading the Finatra test documentation and provided examples, it seems they are focused on testing a server, or a client for a server running locally.

The problem is that in my case the server is external and I do not have access to it. I want to avoid making an actual call to the server from my unit test environment.

Thanks!

Hi Javier -

If the client talking to your service is provided by a module, take a look at override modules. You can use that to provide a fake client for testing purposes.

Hope that helps!

Hi Jordan, thank you for your response.
In fact it is actually the other way around. The service is external, and I just want to test my client.
I need to stub the server responses.

Hi Javier,

Without knowing your exact specifics, you can always create a simple test server, start it in a FeatureTest, configure your client to point to it and write/run your tests. Finatra is ostensibly focused on writing servers but you should be able to easily test a client with a real (dummy) server in a FeatureTest. 

If you just want to mock server responses to your client, then simple unit tests would probably suffice and you don't need anything from the framework.

Thanks,

Thanks much Christopher,
You are right, the best way to go would be to create a test server, and maybe mock different responses with Finatra.
